1968 Ford Mustang — inside shoulder worn out while outside looks fine

I wouldn't throw parts yet. Two 1968 Ford Mustangs can feel identical and have different causes, so measure before you copy someone else's repair. Save the big job until that test fails. If you share a photo of the worksheet, easier to sanity-check. This is the version I'd tell a friend.

Start with the test that can prove you wrong. Write temp, speed, and in-gear vs coast when the 1968 Ford Mustang does it — then decide on parts. If the cheap test changes it, stop and reassess. Time, temperature, and whether it's in gear are the notes that actually help a shop. Worth doing even if the car feels fine right now. Parking it somewhere I can hear it better next time.

This is usually cheaper to test than to guess. Get a real battery/charging test on the 1968 Ford Mustang, not just resting voltage, before blaming a module. If the cheap test changes it, stop and reassess. Write the result down so the next test isn't a repeat of the last one. Video is ugly but it shows the hesitation.

Log the conditions before you spend. Two 1968 Ford Mustangs can feel identical and have different causes, so measure before you copy someone else's repair. You'll know quickly if you're on the wrong tree. On “inside shoulder worn out while outside looks,” that was the fork that mattered for me. Write the result down so the next test isn't a repeat of the last one. Wrote this up on my lunch break.

Start with the test that can prove you wrong. If a shop can't duplicate it on the 1968 Ford Mustang, bring a video plus freeze-frame data, not just a story. Don't erase codes until someone who can help has seen them. A shop burned me once by skipping that step. I'd rather pay for diagnosis than a second guess-repair.

I wouldn't throw parts yet. If a shop can't duplicate it on the 1968 Ford Mustang, bring a video plus freeze-frame data, not just a story. If the cheap test changes it, stop and reassess. This is from a 1968 Ford Mustang in Raleigh with 131,000 miles. I'd want that in writing, not as a promise. That's my plan before I call anyone.

I'd want a measurement, not a hunch. Loaded-suspension checks on the 1968 Ford Mustang catch play that a wheels-hanging inspection misses. Save the big job until that test fails. Was this after sitting overnight? No warning lights, which is why I'm documenting it.

Ask what changed right before it started. Swap the cheap/easy piece first on the 1968 Ford Mustang and see if the fault moves. Save the big job until that test fails. Had a similar mess a couple years ago and that's what finally sorted it. Make the next action something you can finish this week. I'm in no rush to be a hero on it.

Intermittent stuff lies if you only catch it once. Loaded-suspension checks on the 1968 Ford Mustang catch play that a wheels-hanging inspection misses. Save the big job until that test fails. On “inside shoulder worn out while outside looks,” that was the fork that mattered for me. This is from a 1968 Ford Mustang in Raleigh with 131,000 miles. That's the sequence I'd use. Doing the boring step first on purpose.
